On discrete subgroups of Euclidean spaces (Lenny Fukshansky, CMC)
Let x_1,...,x_n be an overdetermined spanning set for the Euclidean space R^k, where n > k. Let L be the integer span of these vectors. Then L is an additive […]

Biquandle arrow weights (Sam Nelson, CMC)
Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United StatesMany knot invariants are defined from features of knot projections such as arcs or crossings. Gauss diagrams provide an alternative combinatorial scheme for representing knots. In this talk we will […]

Orthogonality defect and coherence of cyclotomic lattices (Lenny Fukshansky, CMC)
Davidson Lecture Hall, CMC 340 E 9th St, Claremont, CA, United StatesThere are two different measures of how far a given Euclidean lattice is from being orthogonal -- the orthogonality defect and the average coherence. The first of these comes from […]

structural aspects of von Neumann algebras arising as graph products (Rolando de Santiago, Purdue University)
Roberts North 105, CMC 320 E. 9th St., Claremont, CA, United StatesGraph products of groups were introduced in E. Green’s thesis in the 90’s as generalizations of Right-Angled Artin Groups. These have become objects of intense study due to their key roles in topology and group theory. Recently, Caspers and Fima introduced graph products of von Neumann algebras. Since their inception, several structural aspects such as […]
